悬赏园豆:100 [待解决问题]

创建一个具有1000行的数据文件。文件中的每行包含一个教职员工的姓,名,级别以及薪水。第i行的教职员工的姓和名为FirstNamei 和LastNamei。级别随机产生为assistant(助理),associate(副)以及full(正)。薪水为随机产生的数字,并且小数点后保留俩位数字。对于助理教授而言,薪水应该在50000到80000的范围内,对于副教授为60000到110000,对于正教授为75000到130000.将生成的数据保存文件为salary.txt。 下面是一些示例数据:
FirstNameI LastNamel assistant
60055.95
FirstName2 LastName2 associate
81112.45

FirstName1000 LastName1000 full
92255.21

大数据的分析
编写一个程序,分别显示salar.txt文件中助理教授,副教授,正教授各个类别的总薪水,各类别的平均薪水以及各类别的职工数。

用java语言写。

对这个薪水比较感兴趣。
为啥搞txt?
效果

附上c#代码:

using System.Collections.Generic;
using System.IO;

using System.Linq;

        readonly static SalaryBand full = new() { Name = "full", Floor = 75000, Upper = 130000 };
        readonly static SalaryBand[] salaryBands = new SalaryBand[3] { assistant, associate, full };
